PM in New England

Particle pollution presents a serious air quality problem in New
England. Particle pollution is produced by a wide variety
of natural and manmade sources, including factories, power plants,
trash incinerators, motor vehicles (especially diesel engines),
construction activity, fires, and natural windblown dust. In
the wintertime, a particular concern is fine particles released
by smoke from fireplaces, wood stoves and outdoor burning. This
smoke can accumulate, especially in low-lying areas, when a temperature
inversion traps a layer of cold air near the ground.
